Kevin Green expects a "cautiously optimistic" finish to the year for the market, despite potential pain points on the horizon, including a government shutdown and earnings season. KG notes that a short shutdown would likely be shrugged off by the market, but a longer one could have broader economic implications. He also points to the strength in technology stocks, particularly in the A.I. and semiconductor spaces, with Nvidia (NVDA) and Broadcom (AVGO) getting price target hikes from analysts. KG's S&P 500 (SPX) targets are 6685 to the upside and 6600 to the downside, warning of potential volatility around the quarter's end.
