WhyThat
Free weekly/daily email explaining why your portfolio moved
WhyThat sends you a daily or weekly email explaining exactly why your portfolio moved. Real market data, real news from Finnhub, AI-generated explanations specific to your holdings. Built by a 17-year-old over one summer. Free at whythat.org.
I kept checking my portfolio and had no idea why it moved. After competing at the National Personal Finance Challenge at the Federal Reserve and visiting Goldman Sachs as a junior in high school, I realized even people serious about finance struggle to understand daily market movements. So I built the tool I wished existed. A free weekly email that explains exactly why your portfolio moved, backed by real market data and news. Built this at 17 over one summer.
Love the concept, super useful for someone who doesn't want to dig through five news sites after a red day. One thing that would make it even better for me: add a section that flags which holdings had no real catalyst, so I know the price action might just be noise or sector wide moves rather than something specific to the company.
