Abandoning the 2015 forecast is probably the bigger news vs any kind of daily price fluctuations, but the stock fluctuation underscores that this is somewhat big deal.
Sorry if you hold IBM. Oil stocks have been painful for me, I wish I was doing as well as IBM is doing.
Consider, e.g., an asset whose price is just going steadily upwards. Every 3-year period has a low point -- the start of the period -- but there is no point at which you can say "The price of this asset is now at a 3-year low".
edit: FYI, IBM hasn't traded below 170 since Oct 4, 2011. It hasn't closed below 170 since Sep 23, 2011.
The few times in my life I've made money from an "I've got a deal for you phone call" the person on the other end wasn't making money from a cut of my check. Instead, I was making the deal bigger.
Stock market literature is a respectable pony system. The Dow goes up because they drop losers and add winners. The index funds were that were holding AIG didn't get Kraft Foods shares and their investors lost money. I feel I'm just smart enough to recognize that intraday is dead money for the quants in HFT.
What bothers me are per share prices. I don't remember the precise value of any particular stock, so IBM drops $13 means nothing to me. Also that a stock is $500 a share, so it must be good is another thing you see a bunch, so it must be great is another fallacy I see all the time; when really all that matters is the market cap not how many pieces it is divided into.
Edit I think it was $200. See numbers matter.
