I think I have told you it has been my experience that whenever a stock crosses 100 or 200 or 300 for the first time, it nearly always keeps going up for 30 to 50 points and after 300 faster than after 100 or 200. One of my first big coups was in Anaconda, which I bought when it crossed 200 and sold a day later at 260. My practice of buying a stock just after it crossed par dated back to my early bucket-shop days. It is an old trading principle.
