Trip stock: June 23, 2020 over 10% return

I spent more than two hours to work on stock research and my own portfolio. But today I made wrong decision not to purchase TRIP stock. I reviewed the position with over 30% loss after June 5, 2020 purchase. 

I sold 500 shares of SABR but I bet that it will go down and plan to purchase back. Actually I should bet on TRIP stock. 

Trip has same trend as SABR stock on June 23, 2020. I got up too late on June 23, around 7:30 AM, and sell SABR stock around 9:20 AM PST. Totally I did not know the trend of stock TRIP and SABR on June 22, 2020.
