At risk of explaining egg-sucking to grandmas:
Another thing that I have seen over my years in tech (cough, now retired, of course) are share splits.
Again, & in general, often a sign of a company doing well: share price has been rocketing, for example, to $200 a share. They split - the number of shares doubles, but the price halves: no material difference in the market cap of the company, BUT perhaps the share price can continue an upward trajectory - happy days.
In my personal case, on joining a company, I was advised to join ASAP, because within a week, a share split was scheduled to happen. Made quite a material difference to our later situation, even though at the time I really didn't understand it
Of course, a company in trouble might split the other way -
Adam, you are absolutely right that the Nvidia price is a psychological issue.
Many of us struggle to accept that the upward trajectories of several companies can continue without some event. Some youtube experts continuously predict the next market crash....yet here we are.
My view is to take some gains from time to time. A wise head once suggested when things are on an upward path, take perhaps 10% a year to cash: invest it, spend it, but remove it from the vagaries of the market. Of course there are times when hindsight clearly makes that the wrong decision, but sometimes it works, & some of this is "peace of mind".
For us, I like to keep a 'proportion' of our net worth in cash, or cash-like assets (eg, premium bonds, savings accts) - around 10%. If things get out of kilter, that is what I try to gently rebalance. Rightly or wrongly!
