Whats the reasons these 2 stocks prices have been going UP AND DOWN?

Question

BJS AND JASO ?

provide some insights as to why these 2 stock prices moved up or down

Answer 1

Most stocks go up and down. Fluctuations, however do have a comparative benchmark called "beta".

BJ Services (which those in the oil fields often have a crude expression which is due to what BJS does, increases oil field pressure to force out more oil than would flow on its own) is actually going up quite nicely. The 52-week high was about a month ago and it is selling close to that now at just above $30. The low for the 52-week was back in January so BJS is up some 24 percent, year to date. As commonly measured, BJS has a "beta" of 1.16.

JA Solar, meanwhile, is not quite the technical trading star that BJS is, yet the general trend is up and prospects are good. JASO has a beta of 1.7, showing even wilder swings.

Just for grins, 3M has a beta of 0.77, yet the graph on this docile giant still shows a great deal of raggedness, but the swings are of shorter swings. ESMK, Esmark, meanwhile, has a beta of 1.46 and shows similar trends of fluctuations, it is a lesser company than your JASO, but JASO is a better company.

You've a couple of good companies, I think they are worth holding (and you might buy more when one of the down swings happens, that averages down your cost bases).

Answer 2

Rabbit knocked it out of the park.  The only thing I would add is to make sure you identified why you get into any stock position and more important what signals your exit.  Stocks do move in a sorts of patterns.  A good trader uses those stock swings to identify support and resistance.  They combine that with technical indicators to fine tune their entries and exits.
