Saag paneer is not a side dish in India, or in any Indian restaurants I've been to in North America. Saag paneer served with rice or naan forms a meal just like butter chicken with naan. That Indian meals often have multiple entrees does not make saag paneer a side dish in any way.
All time high has nothing to do with what the value will be anytime tomorrow. If you can't predict the value for the next day, what is the point of waiting to time the market. Besides, even the worst timers of the market do pretty well with disciplined investments.
I don't think robo-investors do that. They rebalance your portfolio (and that too not very often), and buy more of the cheaper stuff, so more in line with your GP than your parent comment.
