retail traders can push up MRVL stock again above EMA 50 or above EMA 20 alone without institutional buyers next two weeks?

 No, retail traders cannot sustainably push Marvell Technology Inc (MRVL) stock above its 20-day or 50-day Exponential Moving Averages (EMA) alone over the next two weeks.

With a massive market capitalization of $189.96 billion and institutional entities controlling over 81% of the stock float, retail trading volume lacks the sheer capital required to fight institutional directional trends. While retail momentum might spark short-term intraday volatility, sustaining a breakout over major moving averages during a broader market reset requires the deep pockets of large asset managers.

Following Marvell's Q2 earnings report on August 27, 2026, the stock fell over 8% to around $216.62 due to an unexpected contraction in projected Q3 margins. This post-earnings decline has dragged the price below its key short-term moving averages. [1, 2]

Why Retail Traders Can't Do It Alone

Overwhelming Institutional Dominance: Mega-institutions like BlackRock Inc., Vanguard, and FMR LLC hold the vast majority of shares. Retail orders make up a tiny fraction of daily dollar volume. [1, 2]
Premium Valuation Hurdles: MRVL currently trades at an elevated price-to-earnings (P/E) ratio above 74x. Retail buyers are highly sensitive to valuation corrections when the broader chip sector shifts into "risk-off" territory. [1, 2]
Algorithmic Resistance: Quantitative and institutional trading programs use the 20-day EMA and 50-day EMA as rigid automated sell triggers during downswings. Retail capital is insufficient to break through these programmatic sell blocks.
Delayed Catalyst Timelines: Investors were disappointed to learn that material revenue from the widely covered Google custom AI chip partnership will not hit balance sheets until fiscal 2029. This long timeline gives big funds a reason to sit on the sidelines for now. [1, 2, 3]
