it have been a rollercoaster ride at times. going through the journey where the market is apparently going nowhere or sideways which is a bit like the flat portion of the roller coaster which then have some excitement with some sharp up and downs such as the fed rate cut rally and the buy anything China rally and also the very sharp Japanese stock crash and recovery (forgotten what happened over there and what is a good name to call it).
how does simple returns and time weighted differ? no idea ...
