<prompt> Human: First time poster, beginning investor here a few k, nothing too big to start. Im looking at a few stocks long term, larger companies. UA and Tesla for example, and I notice that these stocks have fluctuations of around 10 over a few weeks. Im wanting to buy these stocks for long term investment. Im wondering: is it worth it to wait a few weeks to see if it dips to a lower fluctuation before buying but risk having it go up, or just to buy it and forget about it, since Im holding for long term anyway?ie. I waited too long for Tesla a couple of months ago, and bought at around 260. But if I waited even longer, its now back to 230s... So I feel like kicking myself for both waiting too long, and not waiting longer...Thanks in advance!  <response>: We do not advocate speculating on individual stocks here. If you want to waste your money on that, head over to rinvesting. Its also not a good idea to try to time a stock or the market as a whole, mostly because its impossible to do reliably over the long term.If youre interested in investing properly for the long term, please read the information found in the FAQ particularly I Have X ... What Do I Do With It?! and the Long-Term Investing Start-Up Kit You may find Your 401k and You: Basic Information and Your IRA and You: Basic Information worth a read as well.
