NEW YORK (TheStreet) -- It was a hectic month for investors and August isn't shaping up to be any different. Over the past five years, the S&P 500 has declined by an average of 2.5% during August. On Friday, the index slid just 0.2%, while bonds rallied on the day.
On CNBC's "Fast Money" TV show, Guy Adami, managing director of stockmonster.com, said the S&P 500 seems likely to make a run at its prior high near 2,135. He also believes the rally in bonds can continue.
There's been some volatility in U.S. stocks, but not much, added Brian Kelly, founder of Brian Kelly Capital. For now, U.S. equities have been like "Teflon" when it comes to asset classes, he added. But if the U.S. dollar continues to rally, it will likely have a negative impact.
Tim Seymour, managing partner of Triogem Asset Management, agreed about stocks continuing to rise. He likes health care and hospital stocks.
David Seaburg, managing director and head of sales trading at Cowen and Company, said roughly 22% of the health care sector is comprised of biotech stocks. Many of the high-quality biotech names -- Celgene (CELG - Get Report), Amgen (AMGN - Get Report) and Gilead Sciences (GILD - Get Report) -- will likely continue to move higher. Growth rates and product pipelines remains strong, he explained.
The opposite is oil stocks. The commodity suffered from its worst month since 2008 and fell 3.5% on Friday.
Ari Wald, head of technical analysis at Oppenheimer & Company, does not recommend getting long in that sector. He said the Energy Select Sector SPDR ETF (XLE - Get Report) is reminiscent of the financial sector in 2008 and even the tech sector of 2000. While he doesn't expect the energy sector to have quite the same dramatic selloff, he does expect it to head lower. He said $60 would be a reasonable level to which the XLE could decline, roughly 13.5% below current prices.
Tech stocks in 2000 had insanely high valuations, Seymour said. The valuations in energy are actually starting to look attractive. If OPEC decided to cut production, oil prices would rally.
Back in 2008 there was a lot of fear because banks were going bankrupt, Seaburg said. That fear led to a deeply oversold condition, which doesn't seem likely for energy stocks.
However, in the long term -- say, six to 18 months -- investors can buy high-quality oil stocks such as Exxon Mobil (XOM - Get Report) and Chevron (CVX - Get Report) while staying away from exploration and production stocks with weak balance sheets.
Adami is a buyer of refining stocks, saying investors can stay long Tesoro Corp. (TSO) and Valero Energy (VLO - Get Report) as long the stocks stay above $95 and $65, respectively. The energy sector seems likely to move lower, he added.
For their final trades, Seymour is buying Exxon Mobil and Seaburg said to sell Zillow (Z - Get Report). Kelly is buying the Market Vectors Gold Miners ETF (GDX - Get Report) and Adami is a buyer of Pfizer (PFE - Get Report).
