Just 3 days ago, I sold my investment in Nvidia Corporation. To summarize what I did, I used almost 6% of my family fund to buy the stock at $550 per share. Just 4 weeks later, I exited the stock by shorting its call options with strike price of $710 at $8.50 each. The call options got exercised, so effectively, I sold the stock at a price of $718.50. All these happened under 40 days. In that short paragraph, there are multiple things that seem atypical of my investment style

• I bought a stock that looked very expensive (trailing PE ratio of 79!)
• I didn’t do a proper discounted cash flow valuation of the company
• I traded in a really short time frame

I felt a bit FOMO when the stock surged further after I sold it. A friend comforted me by saying it was still a good trade. My wife reminded me of the reality that I don’t know how to time the market....
