NEW YORK (TheStreet) -- Shares of National Bank of Greece  (NBG) are down 5.37% to $1.14 in morning trading today as Greek markets decline.

The Global X FTSE Greece 20 ETF (GREK), designed to reflect broad based equity market performance in Greece, was down 3.32% to $10.20.

The Greek markets reacted as Euro zone leaders plan to tell Greece today that time and patience are "running out" for its leftist-led government to implement agreed reforms to avert a looming cash crunch that could force it out of the single currency, Reuters reports.

Greek Prime Minister Alexis Tsipras has reportedly requested a meeting with the leaders of Germany, France and the main EU institutions to advocate for the country as it seeks more short-term funds.

"I will repeat to him what I've already told him twice: Greece must undertake the necessary reforms, Greece must ensure that the commitments it made to the Eurogroup in 2012 and more recently are followed up on," European Commission President Jean-Claude Juncker told France's Europe 1 radio, according to Reuters.

Separately, TheStreet Ratings team rates NATIONAL BANK OF GREECE as a Sell with a ratings score of D. TheStreet Ratings Team has this to say about their recommendation:

"We rate NATIONAL BANK OF GREECE (NBG) a SELL. This is driven by several weaknesses, which we believe should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks we cover. Among the areas we feel are negative, one of the most important has been a generally disappointing historical performance in the stock itself."

Highlights from the analysis by TheStreet Ratings Team goes as follows:

  • NBG's stock share price has done very poorly compared to where it was a year ago: Despite any rallies, the net result is that it is down by 77.41%, which is also worse that the performance of the S&P 500 Index. Investors have so far failed to pay much attention to the earnings improvements the company has managed to achieve over the last quarter. Naturally, the overall market trend is bound to be a significant factor. However, in one sense, the stock's sharp decline last year is a positive for future investors, making it cheaper (in proportion to its earnings over the past year) than most other stocks in its industry. But due to other concerns, we feel the stock is still not a good buy right now.
  • NATIONAL BANK OF GREECE reported significant earnings per share improvement in the most recent quarter compared to the same quarter a year ago. The company has demonstrated a pattern of positive earnings per share growth over the past two years. However, we anticipate underperformance relative to this pattern in the coming year. During the past fiscal year, NATIONAL BANK OF GREECE turned its bottom line around by earning $1.98 versus -$27.80 in the prior year. For the next year, the market is expecting a contraction of 71.7% in earnings ($0.56 versus $1.98).
  • NBG, with its decline in revenue, underperformed when compared the industry average of 2.3%. Since the same quarter one year prior, revenues fell by 30.3%. The declining revenue has not hurt the company's bottom line, with increasing earnings per share.
  • Net operating cash flow has increased to -$344.49 million or 38.74% when compared to the same quarter last year. Despite an increase in cash flow of 38.74%, NATIONAL BANK OF GREECE is still growing at a significantly lower rate than the industry average of 296.61%.
  • 36.50% is the gross profit margin for NATIONAL BANK OF GREECE which we consider to be strong. It has increased from the same quarter the previous year. Regardless of the strong results of the gross profit margin, the net profit margin of -5.49% is in-line with the industry average.
