The example of Amazon should scare everyone, and but also inform and enrich everyone. This volatility happens to EVERY SINGLE successful stock. Up and down up and down. Look at Cisco, Microsoft, Intel, Amazon, Google, Tesla, et al.
Those who held on, and systematically bought, or simply bought at opportune times from time to time, were quite enriched. Those who sold at the top were probably quite enriched (but years later disappointed).
On the other hand, you can say that about many stocks.
Look at AOL. But as we have discussed, AOL was in the midst of being demonstrably disrupted by broadband.
Intel, same thing but with mobile.
Other times, you misrecognize a stock because you have your heart in the stock (not your head). And sometimes it is just bad luck.
Amazon happens to be good luck. Remember, if not for AWS, Amazon would not be close to the stock it became again. Yet most people would have held simply because it was the dominant etailer, and then got lucky AMZN became more.
SHOP vs. AMBA. I agree, not much to compare. SHOP has a large competitive moat. AMBA does not. SHOP has a TAM so large that not even Burt Hochsfeld will guesstimate it. AMBA, not the same.
But, that makes us feel good. Look at Amazon, all powerful Bezos and Amazon. The stock has been crushed multiple times throughout the years. Toss AMBA aside, it WILL also happen to SHOP. When will it happen to SHOP though? Is now the peak, or will it be when SHOP has a marketcap of $15 billion and crashed back to today’s valuation? Dunno.
What I do know is that if I sell SHOP now, and lock in my profits to date, I will pay 30-40% or more on taxes as the capital gains will be added to my income.
However, if you have held SHOP for more than a year, you can get long-term capital gains treatment (20%, and expected to fall if Trump tax plan is enacted), or if you hold it in a SEP account (0% tax), then you will have more freedom.
This is why I say, that too often we do too much, and fretting and doing all the activity actually hurts our long-term returns. It takes a lot of activity and fretting to find and buy long-term winning companies, but once you have one, perhaps we are best off leaving them alone.
