Here's a technical look at how to trade seven stocks that were seeing big trading volume on Friday following the Brexit vote.

  • Nearest Resistance: $213
  • Nearest Support: $202.50
  • Catalyst: Brexit Vote

Leading off the list of the most active stocks in U.S. markets last week was the SPDR S&P 500 ETF (SPY) - Get Report . As the go-to proxy for "the stock market," it's not surprising that SPY was the most heavily traded issue on the NYSE to end the week. The big ETF (like the big index itself) shed nearly 3.7% during the session on Friday, making it one of the worst day for stocks in almost a year -- and the worst day in some individual sectors over a much longer timeframe.

Technically speaking, though, SPY looks down, but not yet out. That's because SPY is catching a bid at trend line support, the price floor that's connected all of the major lows that the big index has posted since March. If that support level gets violated in the week ahead, it's a bearish signal. That said, if SPY can catch a bid here at support, consider it a buying opportunity.

Bank of America

  • Nearest Resistance: $14.50
  • Nearest Support: $13
  • Catalyst: Brexit

The financial sector posted some of the worst losses Friday, falling 5.4% as a group in the worst day since August 2011. But big bank Bank of America (BAC) - Get Report  had it even worse. The banking giant was the most actively traded stock in the sector, and it lost almost 7.5% of its market value during the session. From here, investors might want to view BofA with some caution.

While Bank of America had been in an uptrend for the last few months, shares broke through the bottom of the trend earlier in June. While shares settled in at support at $13 to end last week, the uptrend that had been pushing shares higher is over. Shares could still have considerable downside risk from here, especially if $13 gets violated.

VelocityShares VIX 2x Short-term ETN

  • Nearest Resistance: $3.50
  • Nearest Support: $2
  • Catalyst: Brexit

One of the few beneficiaries of the big downside move in the markets Friday was the VelocityShares 2x VIX Short-term ETN (TVIX) - Get Report . The exchange-traded note, which tracks double the daily return of the VIX Volatility Index, rallied 40.85% on Friday. Still, long-term, the trajectory of TVIX is still down in 2016. But if markets continue their slide on macro concerns surrounding the Brexit, that could change.

An important note about this exchange-traded note is the fact that TVIX doesn't have conventional support and resistance levels like a normal stock. Since the price action in TVIX is determined by a statistical formula, not directly supply and demand from market participants, it's important not to try to use conventional technical tools on this unique ETN.

  • Nearest Resistance: $11
  • Nearest Support: $8.10
  • Catalyst: Brexit

As hard as U.S. financial stocks took the Brexit vote news, Eurozone and U.K.-based financial firms took it worse. Case in point: $38 billion financial services giant Barclays (BCS) - Get Report  lost more than 20% of its market value on Friday, selling off to test 52-week lows.

Previously, Barclays had actually looked strong from a technical standpoint, but last week's price action changed all of that. Shares gapped down to test 52-week lows at the open on Friday, a level that, if violated, would open up considerable downside risk for this banking giant. It makes sense to steer clear of this stock for the time being.

Banco Santander

  • Nearest Resistance: $4.77
  • Nearest Support: $3.70
  • Catalyst: Brexit

Banco Santander (SAN) - Get Report  is another Eurozone banking stock that got stomped on during Friday's session. Santander dropped 20% during the trading day, retracing back to 52-week lows at $3.70. While shares worked their way up from there during the course of Friday, that's not exactly a silver lining - shares are teetering on the edge of a more substantial breakdown from here if $3.70 gets violated in the week ahead. This is another Eurozone bank to avoid this week.

Ford Motor 

Image placeholder title
  • Nearest Resistance: $13.50
  • Nearest Support: $12.50
  • Catalyst: Brexit

Here at home, Ford Motor (F) - Get Report  was a high-volume mover to end last week, shedding 6.6% of its market value, thanks in large part to substantial exposure to Europe and the UK. Notably Ford Europe posted substantial sales gains earlier in 2016, and the unit returned to profitability last year. The drama surrounding the Brexit news is a notable step back after Ford's big progress in the region.

From a technical standpoint, the uptrend that Ford had been trading in is busted thanks to Friday's big leg down. But while shares are certainly feeling the impact of the Brexit, it's a little early to count Ford out at this point; shares are still making higher lows that could squeeze them closer to another test of their resistance range up at the $13.50 to $14 level. On the flip side, if Ford violates the $12.50 level here, shares look likely to test prior lows from February at $11.

VanEck Vectors Gold Miners ETF

  • Nearest Resistance: $27
  • Nearest Support: $22
  • Catalyst: Brexit

One of the few winners across the board in the wake of the Brexit was gold -- and most notably the VanEck Vectors Gold Miners ETF (GDX) - Get Report , which ended the week as one of the NYSE's most active stocks. GDX rallied nearly 6% on the Brexit vote news, as gold became the go-to risk-off trade.

Technically speaking, GDX hasn't been a stranger to upside in 2016. In fact, this big exchange-traded fund has nearly doubled year-to-date, and after tracking sideways in a wide channel since early May, this fund is on the edge of a breakout through resistance up at $27. While GDX traded above that $27 price ceiling momentarily in Friday's session, it closed below it, delaying the possibility of a breakout for at least another session or two. That said, it makes sense to keep a close eye on how GDX trades in relation to $27 for the week ahead.
