When 2025 opened, there was plenty of talk of a boffo year for stocks. Tax cuts were coming. Deregulation was coming. Maybe the Federal Reserve would cut interest rates more.

So, there was talk the Standard & Poor's 500 would end the year possibly at 7,000 or higher, which would mean a 19% gain on the year.

Yes, there might be some tariff increases, but no one — but no one — expected the panic that overtook markets when President Trump unveiled his tariff plans on April 3.

The S&P 500 fell as much as 10.4% in the next two days.

The president then dialed back the tariff increases, subject to getting trades negotiated by July 9.

And, lo and behold, the S&P took off. From an April 7 low, the index has roared back, rising nearly 28% and ending Friday at a record 6,173 after reaching an intraday high of 6,188. 7,000 may seem over-the-top, but . . .

Trading in stock futures late Sunday suggested stocks will open higher on Monday.

At 6:25 pm. EDT, S&P 500 futures were up 6 points to 6,230. Nasdaq-100 futures added 25 points to 22,780. Futures trading in the Dow Jones Industrial Average were up 171 points to 44,295.

For the quarter so far (with one day to go), the S&P 500 is up 10%. It's up 4.4% in June and nearly 5% on the year.

The year-to-date return is about the same at the Nasdaq Composite Index; the Nasdaq-100's gain is 7.2% on the year and 17% for the quarter.

So, if the S&P 500 hits 10% gains per quarter for the rest of the year, the index would finish 2025 at, maybe, 8,200, a gain of some 40%.

If you think that's doable, we can think of a bridge you might buy in Brooklyn.

In short, we're being a tad silly.

Nonetheless, the S&P 500 will end the quarter higher, with the technology sector up 21% and the industrial sector up 12%.

Techs are led by Seagate Technology  (STX) , up more than 60%, Broadcom  (AVGO) , up 61%, and Jabil  (JBL) ., up 56% Palantir  (PLTR)  is up about 45%. Nvidia  (NVDA) , Microsoft  (MSFT)  and Meta Platforms  (META)  are up 46%, 32% and 28%, respectively.

The industrial sector has risen because of gains in a number of defense and related companies, including Boeing  (BA) , naval ship builder Huntington Ingalls  (HII) , L3Harris Technologies  (LHX)  and Howmet Aerospace  (HWM) .
