obviously, you are a novice. if you do indeed are lucky enough to own maxim, put it away and stop worrying. maxim, along with adi and lltc are premier chip companies. their products are not commodities and are not subject to big pricing swings. during the tech meltdown of 2000, these companies remained profitable even in the worst of times.
I agree, the pure analog companies are run on continuous profitable quarters. There must have been a recent large or several large investor(s) that have decided to reduce or eliminate their investment in Maxim. The stock will cycle back to a fairer value over the next several weeks/months as it has customarily done. There is insignificant insider selling because the insiders realize better prices are soon to follow. The analog semis tend to rise during the Summer/Fall season. The PE and PEG ratios are at all time lows and if cash is taken into account, the numbers would be improved by about 10%. A PE of 20 for Maxim with its profit and growth prospects is in my opinion, a time to purchase.
