Been scared to reinvest my 401k, best investing resources used to make decisions?

Hi, I was laid off so I switched my 401k to an IRA and I haven’t reinvested it yet because it was losing money since the beginning of the year while it was still in my old employers plan (before it was like 16% earnings for the couple years prior) and the political climate has me nervous about losing more money. Still, I know I need to reinvest it so I would like to know the best resources you all use to make investment decisions, which sources give you the best unbiased data on companies and just anything else that could be helpful in making my decisions. TIA
