<prompt> Human: Hi everyone, as the title states, Id like to invest in oil. Im young 24 and can handle the current volatility, but I know that it is undervalued so I would like to take advantage of that. Ive got 2000 to invest right now and could potentially contribute more over time. Doing a brief search, Ive found a few ETFs that look like they could be a good choice. These are the Vanguard Energy ETF, Energy Select Sector SPDR, and Fidelity MSCI Energy Index. Low expenses are very important to me. Id like something that emulates the global crude oil market, however, and these seem to only cover US and the energy market overall. Any suggestions on other low cost funds that would be a closer emulation of crude oil only? Otherwise, what do you think of these funds?Thanks for reading  <response>: but I know that it is undervalued No you dont.
