Is it time to be cautious?

I have invested my long term money in SIPs in 4 balanced funds. When all market indicators are positive - EPF money entering the market, domestic investors increasing SIPs, US markets touching new highs, interest rates falling, oil prices remaining stable, government policies improving, shouldn't ordinary investors be cautious? How do they do this? Do fund managers do anything to reduce risk?
