The stock was up more than 1.8% in pre-market trading



If you were thinking of selling Apple AAPL short, this might not be a good week to do it, what with analysts raising their share price targets and a big product launch set for Thursday.

After hitting $275 in intraday trading Friday and closing at $274.07 — its second record high in as many days — the stock was on the rise again in pre-market trading Monday.

Apple opened on the Frankfurt exchange at $279.76, up 1.81%. It hit a intraday high of 279.01 in New York before skidding south. It closed Monday at $270.17, down 1.5% for the day.
