....A lot of people are in at 40-55 dollar range. While you see a 52 week high, the rest of the shareholders see no hope for a recovery to the levels they bought in at.
Before you blow all of the money daddy gave you, you better look closer at what and who you are investing in. If you're looking for 2 & 3 dollar pops and then retracements this might be OK. But, forget about long term appreciation, theres no sales growth here.
First off, if you bought 1 share each of CSCO INTC MSFT AMZN & YHOO five years ago your investment would have grown 500%. I'll take that return.
Second, I won't dispute that people will look at more energy efficient appliances when fuel prices are high. But, no one will throw out a good running unit for a more efficient one. The cost/savings tradeoff doesn't make sense. People don't stay in the same house very long and the savings of $100 - 200 per year isn't worth the thousands to install a new unit. This is just wishful thinking on a PR release.
Lastly, you must be a short term speculator. The stocks you mentioned have performed well, except for this year. You buy quality companies, with quality leadership and a competitive advantage and they won't let you down. Do you even know if York has any of these? Or, are they losing ground to their competition?
