RE:RE:RE:CasinoI might add, this automated trading does not necessarily mean it is entirely disconnected with fundamentals. Some of the algos likely include macroeconomic/micro data and other fundamental statistics in their code. (While other codes might be sheeps using solely technical indicators.) There's also the fact that the relative attractiveness of owning AltaGas decreases when the rest of the market drops. Also the market risk premium might be going up, thus the WACC might go up too and change the discount factor used.
