<prompt> Human: Im quite novice with investing, but was hoping someone could help me wrap my head around this. Im invested in a mutual fund that is focused on semiconductor technology; it was decimated in value today. Im just confused on how this investment could lose its value so sharply. Ive noticed fluctuations in value throughout the year, particularly in this and similar investments, but have not seen such a drastic plummet.Any help would be appreciated EDIT: 10 for 1 stock splitThanks guys  <response>: Its fine, it was a split. Just relax and on Monday you should see it back to normal with you now owning 10x as many shares.
