"It was an old trading theory of mine that when a stock crossed $100, $200, or $300 for the first time, the price doesn't stop there but goes a good deal higher, so that if you buy it as soon as it crosses the line, it is almost certain to turn a profit."
Jesse Livermore
Of course, the same goes for 1k, 2k, 3k...
