MRVL stock | Tripled in 2026 | June 2 2026
Nvidia's Jensen Huang Says This 'Essential' Company Is Primed to Join the $1 Trillion Club
Key Takeaways
- Marvell shares are soaring Tuesday after a fresh vote of confidence from Nvidia CEO Jensen Huang.
- Huang said Marvell, which Nvidia has invested in, could be "the next trillion-dollar company" because of how important its connectivity equipment is to the way AI data centers are evolving.
Could AI chip designer Marvell Technology be the next member of the trillion-dollar market cap club?
Shares of Marvell (MRVL) jumped over 21% to a fresh record in early trading Tuesday, after Nvidia CEO Jensen Huang said Marvell—which Nvidia has invested in—could be "the next trillion-dollar company."1 Nvidia (NVDA) shares were up about 1% recently, after climbing 6% yesterday.
Huang, who appeared alongside Marvell CEO Matt Murphy at the Computex conference in Taiwan, said Marvell's networking connectivity equipment makes it "essential" for the way AI data centers are evolving.
Marvell's market capitalization, which recently hovered around $233.68 billion, is still well off that mark, though the shares have more than tripled in value this year, as investors cheered its surging sales on strong AI demand and support from partner Nvidia.
Nvidia invested $2 billion in Marvell back in March, and expanded its partnership with the company to add Marvell's custom chips to the products it offers to customers looking to outfit their AI data centers.

解析HPE当前的关键技术支撑位(Support)与阻力位(Resistance)
解析HPE当前的关键技术支撑位(Support)与阻力位(Resistance)
- 第一阻力位:$61.50 - $62.00(盘后密集高点与整数心理关口)
- 逻辑:盘后股价最高冲至 $61.30 附近。正式开盘后,多空双方在 $62.00 这一整数大关附近会有一轮心理层面的博弈。 [1]
- 第二阻力位:$65.00(短期筹码上攻目标)
- 逻辑:若开盘后轧空(Short Squeeze)动能延续,衍生品市场的做市商为了对冲看涨期权(Gamma Squeeze)会迫使买盘继续推高股价,下一个心理博弈点将直接移至 $65.00。
- 第一支撑位:$52.20 - $55.00(潜在的回踩震荡区间)
- 逻辑:根据机构在中期趋势中的均线交叉测算,上方强阻力转化而来的中继位大约在 $52.21 附近。如果开盘后遭遇短线获利回吐(Profit-taking),该位置是多头第一道坚实的防线。 [1]
- 核心支撑位:$47.00 - $48.00(前高及跳空缺口上沿 —— 极强支撑)
- 强力趋势支撑:$43.00(财报前的原始震荡中轴)
- 观察开盘前15分钟的量价行为:如果开盘后价格站稳在 $61.30 之上,说明场外资金在指引上调的刺激下正进行“估值重塑(Re-rating)”,可以顺势看高至 $65.00。
- 防范隐含波动率崩溃(IV Crush):如果你持有期权,财报利好兑现的瞬间,期权波动率会快速下跌。此时直接追高远期虚值期权(OTM Call)风险极高,通常利用股票正股或回踩支撑位时布局更为稳妥。
how to restore confidence in trading stocks
To restore your trading confidence, take a strategic break from trading to clear emotional stress, radically reduce your position sizes to ease psychological pressure, and focus on the flawless execution of your trading plan rather than immediate financial profits. [1, 2, 3]
- Stop Trading Temporarily: Step away from the charts for a few days to a week. This stops the bleeding from revenge trading or impulsive moves driven by desperation. [1, 2, 3, 4]
- Audit Your Rules: Write down all the constraints you've placed on yourself. Ask where these rules originated and whether they are still relevant or if they are simply a product of past panic. [1]
- Trade Tiny Amounts: Drop your trade sizes to amounts where a loss is an inconvenience rather than a catastrophe (e.g., \(\$20\) - \(\$100\) trades). [1, 2]
- Use Paper Trading: Consider using a simulator (such as a paperMoney account on platforms like thinkorswim) to practice stress-free execution and form positive habits without risking real capital. [1]
- Reward the Process, Not the Profit: Redefine a "win." If you perfectly followed your system's entry, stop-loss, and exit criteria—and managed your risk—that is a massive victory, regardless of whether the trade ended in a profit or a loss. [1, 2]
- Narrow Your Focus: Don't try to trade every market. Stick to a single strategy, timeframe, and one or two stocks to slowly build your consistency. [1]
- Journal Every Trade: Write down exactly why you entered, how you felt, and the outcome. Reviewing this data allows you to identify mistakes objectively without being overly self-critical. [1, 2]
- What is your preferred trading style (e.g., day trading, swing trading, long-term investing)?
- Have you been keeping a trading journal to review your past setups?
- Would you like strategies on how to size your positions correctly to manage risk?
Tech HPE skyrockets 30% on biggest earnings beat since 2018
- Hewlett Packard Enterprise reported blockbuster second-quarter earnings results.
- Revenue was up 40% from a year ago and the tech company posted its biggest earnings beat since 2018.
- Server revenue was particularly strong, coming in at $5.45 billion, nearly $1 billion ahead of estimates.
Hewlett Packard Enterprise shares skyrocketed 30% on Monday after the tech company posted blockbuster second-quarter results that blew away estimates.
Here’s how the company did compared to LSEG estimates:
- Earnings per share: 79 cents adj. vs. 53 cents expected
- Revenue: $10.68 billion vs. $9.79 billion expected
It was the company’s biggest EPS beat since February 2018.
Revenue was up 40% over a year ago.
Overall Cloud & AI revenue came in at $7.71 billion, topping the StreetAccount estimate of $6.87 billion, but it was the company’s server unit that really impressed. Server revenue, which is a sub-division of the Cloud & AI unit, came in at $5.45 billion, blowing away the $4.66 billion expected by analysts.
HPE bumped its full-year EPS guidance by a full dollar, projecting fiscal year 2026 EPS of $3.35 to $3.45, up from $2.30 to $2.50. The company said it is now tracking two years ahead of its own long-term financial plan.
CEO Antonio Neri told CNBC that traditional server bookings are up triple digits, and it is the biggest backlog the company has ever seen.
“Customers continue to invest in modernizing their infrastructure and scaling AI, and our performance shows the strength of our combined networking portfolio,” Neri said in a release announcing the quarterly results.
糖尿病前期(Prediabetes)
糖尿病前期(Prediabetes)是血糖高於正常值, 但未達糖尿病診斷標準的時期,一般沒有症狀, 卻是很關鍵的時候。患有糖尿病前期的人,還有 機會透過改變飲食、適當運動,或者藥物輔助使 血糖恢復正常,預防或推遲糖尿病。研究顯示, 在真正成為糖尿病之前,胰臟的beta細胞已經損 壞約五成到九成,等到真正糖尿病時其實已經很 嚴重;而長期血糖控制不佳,會引起視力、心 臟、腎臟、神經等各種病變,以及增加中風風 險。
依照美國疾病管制局2014的報告,9.3%(也就是 11個人有一個人)有糖尿病,其中四分之一的人 不知道自己有糖尿病;但是糖尿病前期更可怕, 美國的罹患者高達8600萬人,也就三個人裡面就 有一個;而且嚇人的是,10個病患有9個不知道自 己屬於糖尿病前期。
內科醫師林芷伊指出,糖尿病與糖尿病前期的檢 測很簡單,只要做血液檢查即可。空腹血糖正常 值應該小於100mg/dl;如果是100-125mg/dl之 間,屬於糖尿病前期;126mg/dl以上,就是糖尿 病。若以反應過去三個月平均血糖的指標「糖化 血色素 (HbA1c)」 來看,正常值應該是5.6;5.7 到6.4之間為糖尿病前期;超過6.5為糖尿病。
她表示,亞裔45歲以上、BMI超過23以上者都應 該檢測血糖。最簡單的「治療」,就是立即減 肥,吃得健康、避免久坐、多運動、改變生活習慣;另外,由於吃飯之後1到2小時血糖會開始上 升,因此如果能養成飯後散步的習慣,可以促進胰島素運作,避免身體持續處在高血糖的狀態。如 果試了三個月的生活型態改變,血糖仍無法達到理想指標,則可能需要服藥,以免狀況惡化。其中 一種很受歡迎的藥名為Metformin,可以推遲二型糖尿病的發生時機。
「很多華人很討厭吃藥,寧可吃補品,並不正確。」林芷伊說,其實補品不見得有實際效果,依照 醫學專業建議使用藥物才真正準確;Metformin是第一線用藥,能降低肝臟製造葡萄糖的量、減少腸 道吸收葡萄糖、並且增加人體對糖分的利用,降低血糖。

CRDO stock | Earnings update
Credo Technology (CRDO) stock did indeed drop in extended trading, falling about 14% to roughly $195, despite beating Wall Street's fourth-quarter revenue and earnings estimates. The sell-off was triggered by management's prediction of shrinking profit margins and lowered guidance. [1, 2, 3]
- Earnings Per Share (EPS): Adjusted EPS of \(\$1.16\), beating the analyst consensus of \(\$1.03\).
- Revenue: Reached \(\$437\) million, beating estimates of \(\$431.79\) million and up 157% year-over-year.
- The Cause of the Drop: Credo predicted shrinking gross margins in the current period, which raised concerns about a slower pace of growth.
- Forward Guidance: Q1 fiscal 2027 revenue is expected between \(\$465\) million and \(\$475\) million. [1, 2, 3, 4, 5]
