Given the tight times at the airlines, being an outfit that can provide regulator-approved aircraft replacement parts puts a firm in a favorable position. One of the biggest independent companies in the group is headquartered in Hollywood, Florida.

Heico Corporation (NYSE: HEI) is engaged in the design, manufacture and sale of aerospace and defense products and services. The firm specializes in producing FAA-approved aircraft components, such as combustion chambers and gas-flow transition ducts. It also provides jet engine overhaul and repair services. In addition, the company makes such electronic equipment as power modules and cooling systems. Customers include AMR Corporation (NYSE: AMR), Boeing (NYSE: BA) and UAL Corporation (NASDAQ: UAUA). United Technologies (NYSE: UTX) is a major competitor.

MOST NOTEWORTHY: BEA Systems, Nokia, Medco Health, Quest Diagnostics and PetSmart were today's noteworthy downgrades:

• Citigroup downgraded shares of BEA Systems (NASDAQ: BEAS) to Hold from Buy on valuation following the $17/share offer by Oracle (NASDAQ: ORCL) as they think a public bidding war for the company is unlikely.
  
• ABN Amro downgraded shares of Nokia Corporation (NYSE: NOK) to Hold from Buy on valuation and believes above consensus Q3 results are already priced into shares.
  
• Wachovia downgraded Medco Health Solutions (NYSE: MHS) to Market Perform from Outperform on valuation.
  
• The firm also downgraded Quest Diagnostics (NYSE: DGX) to Market Perform from Outperform, as they believe the prospects from stabilizing volumes and cost savings are reflected in valuation and Street estimates.
  
• Credit Suisse downgraded shares of PetSmart (NASDAQ: PETM) to Neutral from Outperform citing aggressive pricing at Petco, accelerating growth initiatives, limited visibility around expense management, and lack of consistent results.

OTHER DOWNGRADES:

• Methanex Corporation (NASDAQ: MEOH) was downgraded to Sector Underperformer from Sector Performer at CIBC.
  
• Rochdale downgraded Heico Corporation (NYSE: HEI) to Neutral from Buy.

The firm pleased investors last week, when it reported Q2 EPS of $0.35 and revenues of $121.2 million. Analysts had been looking for $0.34 and $114.5 million. Management also guided FY07 EPS to $1.39-$1.41 ($1.40 consensus) and FY07 revenues to $475-$480 million ($473.32M consensus). HEI shares popped into a bullish "flag" consolidation pattern on the news. Prices frequently exit flags moving in the same direction they were traveling when they entered them. In this case, that would be to the upside.

Brokers recommend the issue with three "strong buys," two "buys" and one "hold." Analysts expect a 20 percent average annual growth rate through the next five years. The HEI Price to Book ratio (3.24), Sales Growth rate (31.6%), EPS Growth rate (25.00%), Return on Assets (8.76%) and Return on Investment (11.22%) compare favorably with industry, sector and S&P 500 averages.

Institutional investors hold about 27 percent of the outstanding shares. Over the past 52 weeks, the stock has traded between $26.95 and $43.80. A stop-loss of $36.85 looks good here. Note that HEI shares are highly shorted (May short interest = 35% of float).

Just as concern about the energy inefficiency of incandescent light bulbs (the ones we are most used to) has inspired a world-wide movement to ban them in favor of compact fluorescent lights (CFL), General Electric Co. (NYSE:GE) announced a breakthrough that changes the equation. Its Consumer and Industrial Lighting division has developed an incandescent bulb that will match fluorescent lamp's power miserliness while retaining the quality of light customers are used to.

The high efficiency incandescent (HEI) lamp could also reduce CO² emissions by 40 million tons in the U.S., and the company claims they will also cost less than comparable compact fluorescent lights.

A grass-roots campaign to ban the incandescent light bulb, called the 18Seconds Movement (the average time it takes to change a light bulb is 18 seconds) is supported by entities such as Greenpeace, Yahoo! Inc. (NASDAQ:YHOO), Wal-Mart Stores Inc. (NYSE:WMT), the EPA and the U.S. Department of Energy. Australia has already passed legislation banning incandescent lamps by 2012.

Either way, HEI or CFL, GE is well positioned with lines of products, but this could certainly slow down the rush to legislation worldwide.

For me, CFLs are headache-producers, so if they want my old-fashioned bulbs they'll have to pry my hot, dead fingers from the filaments.
