TSM was upgraded awhile back by ValueLine, and by others to "outperform." (the latter a dubious category, unless it means "outperform our other picks.")
The use of "chips" in automobiles, appliances, robots, etc is still growing exponentially - not to mention changes in Game Consoles. It is quite possible we will soon see the "games" themselves coming out with chips (possibly programable) and few producers have the capacities available to TSM. TSM is the biggest producer in the world.
On the technical side there is steady accumulation, sustained, even OBV, and a leveling of overbot-oversold. Its MACD is turning positive.
