What if the stock goes higher in the future?

What if the stock crashes in the future? Having a guarantee profit sounds like a pretty good deal for some.

Guaranteed profit at the point in time is great for speculators. If you're doing long term investment, realizing profit at random point in time, isn't really that attractive.

What ? Even if you're a long time investor, having an instant 25% guaranteed profit is good as you can sell part of the stock and diversify.

If you follow that logic, each time stock goes after good earnings, everyone should just sell off everything.

They should, provided transaction fees and gains taxes don’t exceed their estimation of the difference in value times the number of stocks adjusted for the time value of money.

People with more complicated positions should consider covariance and factor in uncertainty. But if you’re a shareholder in a single stock and estimate that it’s overvalued by a significant margin, the rational choice is to sell your position, invest in a low risk, highly liquid asset, and rebuy.

Maybe - it depends on the growth prospects of the company - if they were high anyway - then it is better from a capital gains tax perspective to just continue holding the stock until you need the money.

I sold a lot of bitcoin for $20 in 2008, quadrupled my initial investment and felt pretty smart about it.

Good logic. Never sell anything ever because the price might go up.

Not for Twitter's board. They want more, and good for them. In the history of hostile acquisitions, the first offer is never the final one.

It is irrelevant.

I'm sorry that sort of argument makes no sense. Anything could happen in the future, but the price today is what the market judges it to be worth.

The historical price is irrelevant as well. Looking at the historical price is the same sort of thinking that leads to "throwing good money after bad".
