What it means for SIP investors

Tuesday’s market action—where the Dow Jones gained over 1% while tech indices paused—highlights why single-sector concentration carries risk. When high-flying technology leaders consolidate ahead of earnings, attempting to time short-term reversals often leads to costly missteps.
