Quant finance has been doing this stuff for years, high frequency or not, market or non-market data, deep learning or not. In general, quant finance did (big data, cloud orchestration, machine learning, neural nets, realtime web app stuff, etc) before it was cool.<p>Sentiment fund is doing nothing new, and will probably find that 'just deep learn the markets' won't work while getting crushed on non-deep learning things like simulation, portfolio optimizatio, and execution cost.<p>Also, there are already firms that very reliably make vast returns on predicting price moces in the market.<p>Really this blog post is uninformed bloviating on trading and financial markets.
