NEW YORK ( TheStreet) -- TheStreet's Herb Greenberg's Reality Check Thursday details how DRAM pricing are starting to roll over. 

TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, said what he read in Greenberg tells him that lower prices could have a very negative impact on shares of Micron (MU), He said the stock is a favorite among hedge funds. 

That's why he cautioned investors about buying the stock -- it has appreciated over 125% in the past year. 

Cramer also pointed out the recent weakness in the market was initially led lower by Twitter (TWTR). Shares are finally moving higher Thursday -- they were recently up over 4% to $46 -- and could result in a "turn day" for the overall market, he concluded.
